df0e98d408 rhi: Pipeline cache load/save
Add QRhi APIs to retrieve and reload the contents of the "pipeline
cache".

The only API where there is a true pipeline cache is object is Vulkan
(VkPipelineCache). For OpenGL, the other backend where we support this,
it is simulated with program binaries. The Qt 5 style OpenGL program
binary disk cache continues to work like before, but one has now the
option to do things in a more modern, graphics API agnostic way, that
leads to generating a single blob instead of a large set of files in
some system location, allowing easier "pre-baking" of the cache content.

It is expected that Qt Quick exposes the two new functions in form
if QSG_RHI_ environment variables, thus allowing easy testing and
cache file generation.

As an example for the performance improvements this can give, consider
Vulkan, where we do not have any existing persistent caching mechanism
in place:

Running BenchmarkDemoQt6.exe --scene flythrough --mode demo creates 18
QRhiGraphicsPipeline objects from Qt Quick and Qt Quick 3D.

The total time spent in QRhiGraphicsPipeline::create() during application
startup for these 18 pipelines is 35-40 ms on a given Windows (NVIDIA)
system.

When exporting the pipeline cache contents to a file, and then, in a
subsequent run, reloading the cache contents, this is reduced to 5-7 ms
on the same system, meaning we get a 6-7x improvement.

The generated data is always specific to a given Qt version, RHI
backend, graphics device, and driver version. Much of the implementation
consists of adding and verifying the appropriate header to the blobs
retrieved from the driver, to allow gracefully ignoring data that was
generated with a device or driver that differs from the one used at
run time. This should provide robustness, even if the Vulkan or OpenGL
implementation is for some reason not prepared to identity and reject
incompatible cache/program blobs.

c6d6029909 Update QVulkan(Device)Functions to Vulkan 1.2
This also needs improvements to qvkgen. What we get with this patch
are the Vulkan 1.1 and 1.2 core API's additional 11 instance-level
and 30 device-level commands present in QVulkanFunctions and
QVulkanDeviceFunctions.

All of these are attempted to be resolved upon construction. When the
implementation does not return a valid function pointer for some of them
(e.g. because it is a Vulkan 1.0 instance or physical device), calling
the corresponding wrapper functions will lead to unspecified behavior.
This is in line with how QOpenGLExtraFunctions works. The simple
autotest added to exercise some Vulkan 1.1 APIs demonstrates this in
action.

The member functions in the generated qvulkan(device)functions header
and source files are ifdefed by VK_VERSION_1_{0,1,2}. This is essential
because otherwise a Qt build made on a system with Vulkan 1.2
headers would cause compilation breaks in application build environments
with Vulkan 1.0/1.1 headers when including qvulkanfunctions.h (due to
missing the 1.1/1.2 types and constants, some of which are used in the
function prototypes). In practice this should be alright - the only
caveat to keep in mind is that the Qt builds meant to be distributed
to a wide variety of systems need to be made with a sufficiently new
version of the Vulkan headers installed, just to ensure that the
1.1 and 1.2 wrapper functions are compiled into the Qt libraries.

aeeac48cbd AA_SynthesizeTouchForUnhandledMouseEvents: keep correct coordinates
QGuiApplicationPrivate::processMouseEvent() sends a
QWindowSystemInterfacePrivate::TouchEvent if the mouse event is not
accepted and AA_SynthesizeTouchForUnhandledMouseEvents is enabled.
A QPA TouchEvent always contains native touch points, which is why
it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to
translate the QMouseEvent's device-independent position back to the
raw position that it would have had if it came from a real touchscreen.
Therefore we must give that function touchpoints that are actually in
native coordinates.

It may be that some of this transformation could be avoided entirely,
but here we prove that the existing way works correctly, by adding
coordinate checking to the tst_QWindow::mouseToTouchTranslation() test.

c262a69851 rhi: gl: Add some enablers for supporting GL_TEXTURE_EXTERNAL_OES
From QRhi's perspective this consists of two things:

- A shader with samplerExternalOES in it cannot go through the standard
  pipeline. Rather, a QShader with suitable GLSL code in it has to be
  constructed manually. As this is something useful as an autotest
  anyway, add a test case to the qshader autotest that demonstrates
  this.

- When it comes to correctly calling glBindTexture, add a QRhiTexture
  flag. The expectation is that an OpenGL-only client sets this in
  combination with QRhiTexture::createFrom(), thus wrapping an existing
  texture that then gets bound to the GL_TEXTURE_EXTERNAL_OES target
  instead of our usual GL_TEXTURE_2D.

For completeness we also add a SamplerExternalOES variable type to
QShaderDescription, but the sampler type is not actually used by the
QRhi OpenGL backend, as it is the QRhiTexture that defines the
texture target.

042cd97884 rhi: Expose device name, type, and IDs

meaning some fields will only be applicable with certain APIs.

Most of this is already shown upon QRhi::create() as info debug
prints, when enabled. Now expose it all through the QRhi API as
well.

This is useful for printing in qtdiag, and, while it should be
avoided as much as possible, to make decisions about disabling
3D rendering features depending on the driver and GPU in use.

376e3bd8ec Introduce QUrlResourceProvider to load resources for HTML
QTextDocument and the text editor classes suggest to override
their loadResource() methods to provide data associated with
a text document. This approach has the following drawbacks:
- it requires subclassing
- there is no way to set a global resource provider
- QLabel is missing virtual loadResource() method and
  it can't be added without breaking ABI

QUrlResourceProvider is designed to solve these issues.
One should create a derived class that implements
QUrlResourceProvider::resource(). The objects of the derived
class then can be set for any text document.
The default resource provider can be set with
QUrlResourceProvider::setDefaultProvider().
This change also adds QLabel::setResourceProvider(),
which doesn't break ABI.

[ChangeLog][QtGui][Text] Introduced QUrlResourceProvider that allows to
load resources for HTML. It is intended to replace the use of
QTextDocument::loadResource().

d8602ce58b QFont: Prefer setFamilies() over setFamily()
By depending on setFamilies() then we can be sure that font names with
spaces, commas, quotes and so on are correctly handled without being
misinterpreted. For now it will split on the comma when a string
containing one is passed to setFamily. But from Qt 6.2 this will be
removed to preserve the family string as a convenience function.

[ChangeLog][QtGui][QFont] Indicated that setFamilies/families is
preferred over setFamily/family to ensure that font family names are
preserved when spaces, commas and so on are used in the name.

ce29ce586f Revert "Allow QWindowsPipe{Reader,Writer} to work with foreign event loops"
This reverts commit ee122077b0.

Reason for revert: This causes QProcess::readAll() to sometimes
return nothing after the process has ended.

f92e195369 Android: Ensure windows always have a geometry on creation
A QWindow created without an explicit geometry needs to pick up
a default geometry in the platform plugin. If the window has a
maximized of fullscreen window state, it will fill the entire
available geometry of the parent window (or the screen if there's
not parent window).

ee122077b0 Allow QWindowsPipe{Reader,Writer} to work with foreign event loops
When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.

We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).

As a nice side effect, performance (and in particular scalability)
is improved.

Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
   worse. Additionally, it also required a rather egregious hack to
   handle the (pathological) case of a single thread talking to both
   ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
   posting wake-up events to its event loop, and handling I/O on the
   main thread; this performed roughly like this solution , but scaled
   half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
   and still handling I/O on the main thread; this still performed
   comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
   faster with big amounts of data, but scaled slightly worse, and the
   diverging implementations were deemed not desirable.

1869615fc9 QChar: make construction from integral explicit
QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).

David provided the perfect example:

  if (str == 123) { ~~~ }

compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.

Add a macro to revert to the implicit constructors, for backwards
compatibility.

The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.
